iPhone 5 would be Apple's 6th iPhone model

Millions of people will likely buy new iPhones after Apple's expected announcement of a new model on Wednesday, Sept. 12, 2012. The new phones would join some 244 million iPhones already sold since the first one launched in 2007. Some have been lost, some stolen and some are still in use. But it's fair to say that millions of iPhones are languishing in desk drawers or gathering dust. (AP Photo/Itsuo Inouye, File)

The expected iPhone 5 would actually be the sixth iPhone model.

Although Apple hasn't announced a name for its next iPhone—or even confirmed that one is coming—a "5'' in the shadow of an invite for a company event Wednesday suggests that it will be the iPhone 5.
